Disconnecting the Displacement Pump

1.Flush the pump, if possible. Stop the pump at the bottom of its stroke.

WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 8.

Keep hands and fingers away from the priming piston during operation and whenever the pump is charged with air. On the pump downstroke the priming piston extends beyond the intake cylinder to pull the material into the pump. The priming piston works under extreme force. During operation and whenever the pump is charged with air, the priming piston can severely injure or amputate a hand or finger, or break a tool, caught between it and the intake cylinder.

The air motor piston (located behind the air motor plates) also moves when air is supplied to the motor. NEVER operate the pump with the air motor plates removed.

2.Relieve the pressure.

3.Disconnect the air hose. Hold the fluid outlet fitting

(7)with an adjustable wrench to keep it from being loosened while you disconnect the fluid hose. Remove the pump from its mounting. Note the relative position of the pump’s fluid outlet to the air inlet.

4.Using an adjustable wrench, unscrew the coupling nut (104) from the connecting rod (103). Remove the coupling collars (105). Take care not to lose or drop them. See Fig. 4.

5.Hold the tie rod flats with an 11 mm wrench to keep them from turning. Use the wrench (113) provided with the pump (or a 17 mm box or socket wrench) to unscrew the locknuts (106) from the tie rods (102). Carefully pull the displacement pump

(107)off the air motor (101).

6.Refer to page 14 for displacement pump service. To service the air motor, refer to the separate air motor manual, supplied.
